Entropy Clear Casting Fast Hardener (CCF) should be mixed with Entropy Clear Casting Epoxy Resin (CCR) for low build casting applications with thicknesses below 1 inch.
Clear Casting Epoxy Resin (CCR) features low color, excellent air release, and UV stabilizer technology. The result is crystal clear products with excellent color stability. These traits are highly desirable for jewelry, furniture and bar top applications.
Use CCR Resin with CCF fast hardener at a 2:1 mix ratio for medium pot life. For larger castings greater than 1 inch thick, the CCS Slow hardener is recommended instead. The clear casting resin CCR and CCF Hardener have a bio-content greater than 30%, and can be modified with epoxy compatible colorants and fillers.
CCF hardener requires the corresponding size of CCR Epoxy Resin for use (2:1 mix ratio). See chart below.

Safety and Handling Information
Despite the natural derivation of Entropy resin products, exposure to these materials represents hazards typical of all epoxy resins. Exposure should be minimized and avoided through the use of proper personal protective clothing & equipment, and appropriate manufacturing controls. All persons who use, store, or transport these materials should understand proper handling precautions and recommendations, as stated in the SDS (safety data sheets).

Very clear, and hardly any bubbles. I initially bought the slow cure hardener, but exchanged it for the "fast" because until I visited the manufacturer's website I did not have the data. Slow is very slow! This product will not disappoint.

I have been using CCR and CCF hardener for 5 years now. This is the second and last time that I've had a problem with the hardener. The first time all of my pours, which were clear when they went in the molds, turned milky and opaque. My problem this time was drying time. I measured my epoxy and hardener with a scale and mixed per the directions. It took almost three days before I could remove from the molds. Thinking I may have made a mistake measuring I mixed another batch and poured it into the molds. Exactly the same result. Three days to dry enough to remove from my molds. I can't tolerate issues like this when I am trying to produce items to fill orders and meet deadlines.
